If you want to use together with prism

Run npm install prismjs --save-dev

If you want to use together with bootstrap 4

Run npm install bootstrap@4.0.0-alpha.6

Usage in angular-cli project

Please note the instructions below are for projects based on angular-cli, you might need to set up things differently if you're using something else.

Include scripts and styles in build

If you want to use angular exemplify together with prism, make sure to add the prism script and one of the prism theme css files to your .angular-cli.json config, bootstrap.css is optional:

"styles": [
  "../node_modules/bootstrap/dist/css/bootstrap.css",
  "../node_modules/prismjs/themes/prism-coy.css",
  "../node_modules/angular-exemplify/exemplify/css/exemplify.css",
  "styles.css"
],
"scripts": [
  "../node_modules/prismjs/prism.js"
],

Import ExemplifyModule

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { ExemplifyModule } from "angular-exemplify";

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    ExemplifyModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Basic usage

Add exemplify together with [context]="this" to your element like this:

<button exemplify="myExample" [context]="this" class="btn btn-primary" (click)="doSomething()">Action</button>

Where myExample should be a unique identifier for your example, and context should point to the component holding the markup (template).

Using external sources

To keep the examples in sync with your code you should reference the source files. Here's an example based on a app published and deployed to github pages.

externalSources = [{
    "name":"app.module.ts",
    "src":"https://raw.githubusercontent.com/hjalmers/angular-markup-example/master/src/app/app.module.ts"
  },{
    "name":"app.component.ts",
    "src":"https://raw.githubusercontent.com/hjalmers/angular-markup-example/master/src/app/app.component.ts"
  },{
    "name":"app.component.css",
    "src":"https://raw.githubusercontent.com/hjalmers/angular-markup-example/master/src/app/app.component.css",
    "language":"css"
  }]
